Israel's Gaza offensive

Smoke and flames are seen during what witnesses said was an explosion caused by an Israeli air strike on a house in Gaza City

Smoke and flames are seen during what witnesses said was an explosion caused by an Israeli air strike on a house in Gaza City August 23, 2014. Israeli aircraft bombed the Gaza Strip on Saturday and Palestinian militants fired rockets at the Jewish state, the military said, with no end in sight to the deadliest violence between the sides in years. Gaza health officials said five people were killed in an Israeli strike on a house in central Gaza. The Israeli military said it bombed about 20 targets across the Hamas-dominated strip, including rocket launchers and weapon caches.

Human Rights Watch accused Israel of committing war crimes by attacking three U.N.-run schools in the Gaza Strip in fighting in July and August, killing Palestinian civilians who had sheltered there.

The New York-based group issued a report on Thursday that it described as the first in-depth documentation of the incidents, which took place during a 50-day conflict between Israel and Palestinian militants that ended in a ceasefire on Aug. 26. (REUTERS)
